The Evolution of Electronics
Early Beginnings
The journey of electronics began with the discovery of electricity. The late 19th and early 20th centuries saw pivotal developments such as Thomas Edison’s invention of the electric light bulb and Nikola Tesla’s work on alternating current (AC). These breakthroughs laid the groundwork for the modern electronic era.
The Advent of Semiconductors
The invention of the transistor in 1947 by John Bardeen, Walter Brattain, and William Shockley marked a significant milestone. Transistors replaced bulky vacuum tubes, leading to the miniaturization of electronic devices. This era also saw the development of integrated circuits (ICs), which combined multiple electronic components into a single chip, revolutionizing the industry.
